JERUSALEM (JTA) — Three Palestinians were killed and at least 15 injured after clashes with Israeli troops in the Qalandiya refugee camp.

The troops from the Border Police entered the camp early Monday morning, dressed as civilians, in order to arrest a terror suspect who was recently released from an Israeli prison, according to reports.

The troops were surrounded by local residents and attacked with rocks and firebombs, according to reports. The Border Police put the number of Palestinian attackers at 1,500; the Palestinian Maan news agency said there were “dozens.”

The troops, and a rescue force that entered the camp after the violence began, used “crowd dispersal methods,” according to the military, which usually includes rubber bullets shot at demonstrators’ legs and tear gas.

The Palestinian demonstrators also rained boulders and building materials on Israeli Defense Forces jeeps, an incident captured on video.

Ynet reported, citing Palestinian sources, that a meeting between Israeli and Palestinian peace negotiators scheduled for Monday in the West Bank city of Jericho was cancelled after the incident.

“Such a crime proves the need for an urgent and effective international protection for our people,” Palestinian Authority Prime Minister Rami Hamdallah said in a statement issued after the incident.

“The string of Israeli crimes and continued settlement construction represent a clear message as to its true intentions for the peace process,” PA Prime Minister Mahmoud Abbas said.
